Electrospective might have been released for the sake of capitalizing on the widespread popularity of electronic dance music (or EDM). It amounts to a non-definitive, sampler-style trawl through the EMI catalog. Sequenced chronologically, it begins with the pioneering BBC Radiophonic Workshop's 1958 "Doctor Who Theme," and then leaps to 1974 for Brian Eno's "Here Comes the Warm Jets." It covers the '80s, '90s, and 2000s with smatterings of synth pop (Duran Duran), trip-hop (Massive Attack), and dancefloor electronica (Daft Punk, Chemical Brothers), and then grazes from the 2010s (David Guetta, Swedish House Mafia). It goes without saying that EMI labels such as Capitol and Virgin couldn't possibly summarize the history of electronic music, but this set should help younger listeners understand the roots of the 2011/2012 classes of EDM and provoke deeper listening. It's remarkable how so many of these songs were slagged by rockists for being flavors of the month with near-instant expiration dates. Martyn Ware (the Human League, B.E.F., Heaven 17) provides brief liner notes. Seek the two-disc version, which adds choice picks from the likes of Tangerine Dream, the Normal, Inner City, Depeche Mode, and Deadmau5. ~ Andy Kellman
